Users have been experiencing 'dead spots' on the screen, indicating a design flaw or fault in the touchscreen functionality [68991]. (b) The software failure incident related to the operation phase is evident in users' complaints about the touchscreen not responding to touch or having dead spots. This could be due to factors introduced during the operation or misuse of the device, leading to the reported issues [68991].
Boundary (Internal/External) within_system (a) The software failure incident related to the dead spots on the screen of the Samsung Galaxy S9 and S9 Plus is categorized as within_system. The issue with the touchscreen responsiveness was reported by users who experienced dead spots on their screens, indicating a problem originating from within the system itself [68991].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident related to non-human actions in this case is the touchscreen responsiveness issue reported by users of the Samsung Galaxy S9 and S9 Plus. Users complained about 'dead spots' on the screen where parts of the screen were not responding to touch, indicating a hardware or software issue with the touchscreen functionality [68991]. (b) The software failure incident related to human actions in this case involves users attempting to resolve the touchscreen issue by resetting the phone or adjusting sensitivity settings. Additionally, Samsung responded to the problem by investigating and working with affected customers to address the touchscreen responsiveness issues, indicating human intervention in the troubleshooting and resolution process [68991].
Dimension (Hardware/Software) hardware (a) The software failure incident related to hardware: - The article reports that users of the Samsung Galaxy S9 and S9 Plus are experiencing 'dead spots' on the screen, where parts of the screen are not responding to touch [68991]. - Users have complained about dead spots on the screen, indicating a hardware-related issue with the touchscreen functionality of the devices. - Samsung has acknowledged the reports and is investigating the touchscreen responsiveness issues, suggesting a potential hardware problem with the screens of the phones. (b) The software failure incident related to software: - The article does not specifically mention any software-related issues contributing to the touchscreen problems experienced by users of the Samsung Galaxy S9 and S9 Plus. - The focus of the reported incidents is on dead spots on the screen and touchscreen responsiveness issues, which are more indicative of hardware-related problems rather than software-related failures. - Therefore, there is no direct evidence in the article to suggest that the software played a role in the reported failure incidents.
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident related to the Samsung Galaxy S9 and S9 Plus touchscreen issues does not appear to be malicious. Users reported 'dead spots' on the screen where parts of the screen were not responding to touch, leading to complaints and the need for replacements [68991]. Samsung responded by investigating the reports and working with affected customers to address the touchscreen responsiveness issues. There is no indication in the article that the touchscreen problems were caused by malicious intent to harm the system. (b) The software failure incident can be categorized as non-malicious.
